Planetary Final Drive Service Manual Introduction

This manual is a step-by-step guide to the disassembly and assembly of the W3C/W3B Series Torque-Hub

® units. It is designed

for the customer or mechanic who is repairing this particular Torque-Hub

® model.

Users of this manual should note that each part mentioned is followed by an identification number enclosed in parentheses. These part numbers may be referred to in the Parts List and Assembly Drawing sections of this manual.

Specialized tools used to assemble this unit are noted in the assembly procedures and diagrammed in the Assembly Tools section.

Users should familiarize themselves with the procedures for roll and leak testing, as well as bolt tightening and torquing found on the following three pages before starting any repairs.

Standard safety practices should be followed during the disassembly and assembly procedures described. Safety glasses and safety shoes should be worn, and heavy, heat resistant gloves should be used when handling heated components. Be especially alert when you see the word CAUTION. This indicates that a particular operation could cause personal injury if not performed properly or if certain safety procedures are not followed. The word NOTE is used to bring attention to certain procedures or helpful hints that will aid in the disassembly and assembly process.

Planetary Final Drive Service Manual Roll and Leak Test Torque-Hub

® units should always be roll and leak tested before

disassembly (if possible) and after assembly to make sure the unit’s gears, bearings, and seals are working properly. The following information briefly outlines what to look for when performing these tests.

The Roll Test The purpose of the roll test is to determine if the unit’s gears are

rotating consistently, easily and properly. Release the brake by applying 400 Psi to the brake port. To perform a roll test, use the recommended tool from table below (or something equivalent) to apply constant rotational force to the input of the gearbox. If more drag is felt in the gears only at certain points, then the gears are not rolling consistently and easily and should be examined for improper installation or defects. Some gear packages roll with more difficulty than others. Do not be concerned if the gears in the unit seem to roll hard as long as they roll with consistency. Rotate the gearbox both clockwise and counterclockwise the same number of turns as the ratio of the unit. The gearbox ratio is the same number as the last three numbers on the ID tag.

The Leak Test The purpose of a leak test is to make sure the unit is airtight. To perform a leak test use the leak test fixture from the table below. If the tool is not available, the gearbox must be sealed to perform the test. This can be accomplished by assembling the sealed input device onto the gearbox at the input end and replace one of the oil plugs with an air chuck. DO NOT EXCEED 10 PSI PRESSURE DURING THE LEAK TEST. Higher pressure will create a false sealing effect in assemblies with lip-seals. The unit has a leak if the pressure gauge reading on your leak check fitting starts to fall after the gearbox has been pressurized and allowed to equalize. Leaks will most likely occur at the pipe plugs, the main seal or wherever

o-rings or gaskets are located. The exact location of a leak can usually be detected by brushing a soap and water solution around the main seal and where the o-rings or gaskets meet on the exterior of the unit and then checking for air bubbles. If a leak is detected in a seal, o-ring, or gasket, the part must be replaced and the unit rechecked. Leak test at 10 psi for 20 minutes.

Planetary Final Drive Service Manual Tightening and Torquing Bolts

If an air impact wrench is used to tighten bolts, extreme care should be taken to ensure the bolts are not tightened beyond their specified torque. The following steps describe how to tighten and torque bolts or socket head cap screws in a bolt circle.

1. Tighten (but do not torque) bolt “A” until snug.

2. Go to the opposite side of the bolt circle and tighten bolt “B” until equally snug.

3. Crisscross around the bolt circle and tighten the remaining bolts.

4. Use a torque wrench to apply the specified torque to bolt “A”.

5. Using the same sequence, crisscross around the bolt circle and

apply an equal torque to the remaining bolts.

8

Planetary Final Drive Service Manual Lubrication Information

General Properties: The lubricant used in most Torque-Hub

® drives should be petroleum

based gear fluid containing anti-oxidation, anti-foaming and extreme pressure additives. The lubricant should have a minimum viscosity index of 95 cst and maintain a minimum viscosity of 40 cst under normal operating conditions. Some applications require special considerations; consult the machine manufacturer and Oerlikon Fairfield for more additional information.

The table below lists the recommended viscosities for various ambient operating temperatures. These recommendations are based on temperature rise of 50° to 100°F at normal operating conditions.

Footnotes 1. For operation in this ambient temperature range, synthetic oil is recommended with a pour point of

10°F lower than the minimum ambient temperature.

2. For operation in this ambient temperature range, synthetic oil is recommended for proper lubricant life at elevated temperatures.

9

Maintenance Oil amounts for each series of Torque-Hub® drives are indicated in

the appropriate series literature. An initial oil change should be made after the first 50 hours of operation. Subsequent oil changes should be made at 1,000 hour intervals or annually, whichever comes first.

Oil temperatures should be not higher than 160° to 180°F for continuous operation, and no higher than 200°F for intermittent operation. For special applications, high horsepower, high speeds or wide temperature changes, please consult Oerlikon Fairfield.

Oil Fill Level When the Torque-Hub

® unit is mounted horizontally, unless

otherwise specified, the gearbox should be filled half-full of oil. Consult the appropriate series literature for approximate fill volumes. Vertically mounted Torque-Hub

® units may require special

lubrication procedures. Please contact Oerlikon Fairfield for vertically mounted applications.
